brush kit is for final buffing of base to remove wax from grooves or structure

Bonus Benefit for the edge tool: If you don't know what base and side angles your ski/board are set to, this tool can help you find them. Before you start mark the metal edge with a sharpie, start the tool at the lowest angle and see if it removes the marking on your edge. Raise the angle step-wise and repeat until it removes the mark. That is your angle! Record the base/side angles for future reference.

Three Brush Kit Details: Brass brush (10 mm) for renewing base structure, opening pores before you wax (for this step brush in the opposite direction - tail to tip), and brushing hard waxes; Nylon brush (10 mm) that is the workhorse of wax removal. Designed to be stiff enough to remove wax in less passes to save you time; Soft, fine Horsehair brush (8 mm) for removing wax from the fine structure of your base for the ultimate polish!
